Abstract

PURPOSE: To obtain a new compound useful as a thromboxane A2 antagonist for cardiac infarction, cerebral infarction, pulmonary occlusion, thrombosis, renal insufficiency and asthma based on bronchoconstrictive action. CONSTITUTION: This compound is shown by formula I [R<1> is a (substituted) phenyl; R<2> is a 1-15C alkyl, phenyl(oxy), a 1-2C alkylthio; R<3> is H or a 1-5C alkyl; (n) is 0-2] such as (S)-2-(4-chlorobenzene-sulfonylamino)- N-[4-(ethoxycarbonylmethyloxy) phenyl]-3-phenylpropanamide. The compound of formula I is obtained by reacting an N-arylsulfonylaminocarboxylic acid of formula II with a condensation agent such as pivaloyl chloride in the presence of a base such as triethylamine to activate the carboxyl group and reacting the resultant substance with an amino acid ester of formula III.
